As per the subject line; what is the minimum server system requirements? I have tested on a server with 1GB RAM and 1 CPU, according to Digital Ocean Droplets, and struggled to install (error installing Cassandra driver) and ran into 'Internal 500 errors'.
I am testing with 2GB/2CPU which seems to be more stable. What are the experiences from other users? I've not been able to find a definitive specification.
